A 550 Mbit/s real-time visible light communication system based on phosphorescent white light LED for practical high-speed low-complexity application.

open access: yesOptics Express, 2014
In this paper, we first experimentally demonstrate a 550 Mbit/s real-time visible light communication (VLC) system based on nonreturn-to-zero on-off keying (NRZ-OOK) modulation of a commercial phosphorescent white light LED. The 3-dB modulation bandwidth

Indentor-escape, delamination and orogenic collapse of the ca. 600-500 Ma East African/Antarctic Orogen in Mozambique and Dronning Maud Land (East Antarctica) [PDF]

open access: yes, 2010
The East African/Antarctic Orogen (EAAO) is one of the largest orogenic belts on the planet, resulting from the collision of various parts of East and West- Protogondwana between ca. 600 and 550 Ma.

The adsorption of nitric oxide on a silicon (100) 2 × 1 surface studied with Auger electron spectroscopy [PDF]

open access: yes, 1988
We present an Auger electron spectroscopy (AES) study of the adsorption of nitric oxide (NO) on a clean Si(100)2 × 1 surface at 300 and 550 K. Accurate measurement reeveal well resolved fine structure at Auger SiL2.3VV transitions at 62 and 83 eV.

Primary Meningococcal Polyarthritis in an Adult Woman

open access: yesCase Reports in Medicine, 2015
Primary joint infection caused by the Gram-negative bacteria Neisseria meningitidis is rare. Normally, joint involvement comes secondary to meningitis or severe sepsis caused by this agent. When primary arthritis is seen, monoarthritis is the most common

Defining relations for W-algebras from singular vectors [PDF]

open access: yesLett.Math.Phys. 49 (1999) 325-336, 1999
It is shown that the commutation relations of W-algebras can be recovered from the singular vectors of their simplest nontrivial, completely degenerate highest weight representation.

Accumulation and Endocrine Disrupting Effects of the Flame Retardant Mixture Firemaster® 550 in Rats: An Exploratory Assessment

open access: yesJournal of biochemical and molecular toxicology, 2013
Firemaster® 550 (FM 550), a fire‐retardant mixture used in foam‐based products, was recently identified as a common contaminant in household dust. The chemical structures of its principle components suggest they have endocrine disrupting activity, but ...

0-1 laws [PDF]

open access: yesarXiv, 1998
We give a framework for dealing with 0-1 laws (for first order logic) such that expanding by further random structure tend to give us another case of the framework. From another perspective we deal with 0-1 laws when the number of solutions of first order formulas with parameters behave dichotomically.
